PROTON-2764: schedule failed raw connections from pn_listener_raw_accept() so
they can process events and cleanup
> Zombie raw connections
> ----------------------
>
> Key: PROTON-2764
> URL: https://issues.apache.org/jira/browse/PROTON-2764
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.39.0
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
>
> In writing a new threaderciser for raw connections the following scenario can
> result in raw connections that are never scheduled.
> If a pn_listener_raw_accept() fails due to a temporary fdlimit shortage or
> simultaneous close of the listener by another thread, the new raw connection
> is correctly set to an error state but is never scheduled for processing.
> The state machine is never advanced and the raw connection resources are not
> cleaned up. This also causes the PN_PROACTOR_INACTIVE event to be blocked.
